I have heard from people play station 1 games work in play station 2's aswell.
There are very few PS1 games that are compatible with PS2
NO
no, but you can play playstation 1 games on a ps2
Every single Guitar Hero game released for the playstation three, also Guitar Hero 1 & 2 for the playstation two will be compatible if played with a PlayStation 3 console.
No Live is for Xbox 360
You can play some playstation one and playstation two games on your playstation three but I am unsure if the original call of duty 2 can be played on a PS3.
Can you put two games into a ps3? No. Can you run a ps2 game through a ps3? Depends which one it is, the newer ones aren't back compatible with ps2 games.
Unfortunately I don't think you can. The two consoles are using different technologies for the games and I don't see competitors willing to make their systems compatible.
Yes
You can not play any game online with another platform for a number of different reasons. One the games are not compatible and that is why you can not put a Nintendo Wii game in a PS3 or vice versa. Two the Platforms use different networks for the online playing of games Xbox 360 plays on Xbox live and the PlayStation 3 plays on the PlayStation network and the Nintendo Wii will also play on it's own network. Three the consoles are not compatible and that is one of the reasons that the games can not be interchanged, but it is not the only one. So the different games have the same title, but were designed for different platforms and different online networks and will never play each other
Yes.
This depends on the model of your PlayStation three. Sony has issued out four different models of the PlayStation three, these are; The forty gigabyte, sixty gigabyte, eighty gigabyte and the one hundred and sixty gigabyte. The forty and eighty gigabyte were released first, but the forty gigabyte PlayStation three cannot play PlayStation two games. Any other model can.
Yes, and a game for the PSP with the name Sly will be compatible with it when the two are hooked up.
